Abstract
Official abstract text for this publication.
A method of forming a layered coating film includes: coating a workpiece with an electrodeposition coating material to form an electrodeposition coating layer; applying a colored coating material including a white pigment over the electrodeposition coating layer to form two or more colored coating layers that are layered on the electrodeposition layer; and applying a clear coating material over the two or more colored coating layers. The colored coating material includes coating materials respectively applied to form a lower-side colored coating layer and an upper-side colored coating layer of the two or more colored coating layers. A concentration of the white pigment in the coating material applied to form the lower-side colored coating layer is equal to or higher than a concentration of the white pigment included in the coating material applied to form the upper-side colored coating layer.

1 . A method of forming a layered coating film, the method comprising: coating a workpiece with an electrodeposition coating material to form an electrodeposition coating layer; applying a colored coating material including a white pigment over the electrodeposition coating layer to form two or more colored coating layers that are layered on the electrodeposition layer, the colored coating material including a coating material applied to form a lower-side colored coating layer of the two or more colored coating layers and a coating material applied to form an upper-side colored coating layer of the two or more colored coating layers, in which a concentration of the white pigment in the coating material applied to form the lower-side colored coating layer is equal to or higher than a concentration of the white pigment in the coating material applied to form the upper-side colored coating layer; and applying a clear coating material over the two or more colored coating layers. 2 . The method of forming the layered coating film according to claim 1 , wherein the white pigment comprises zinc oxide. 3 . The method of forming the layered coating film according to claim 1 , wherein the colored coating material further includes a resin and a pigment, and an amount of the white pigment added to the colored coating material is equal to or larger than 2.5 mass % based on a total amount of the resin and the pigment. 4 . The method of forming the layered coating film according to claim 2 , wherein the colored coating material further includes a resin and a pigment, and an amount of the white pigment added to the colored coating material is equal to or larger than 2.5 mass % based on a total amount of the resin and the pigment. 5 . The method of forming the layered coating film according to claim 1 , wherein the two or more colored coating layers comprise two colored coating layers that are the lower-side colored coating layer and the upper-side colored coating layer, and the white pigment is included solely in the lower-side colored coating layer. 6 . The method of forming the layered coating film according to claim 2 , wherein the two or more colored coating layers comprise two colored coating layers that are the lower-side colored coating layer and the upper-side colored coating layer, and the white pigment is included solely in the lower-side colored coating layer. 7 . The method of forming the layered coating film according to claim 3 , wherein the two or more colored coating layers comprise two colored coating layers that are the lower-side colored coating layer and the upper-side colored coating layer, and the white pigment is included solely in the lower-side colored coating layer. 8 . The method of forming the layered coating film according to claim 4 , wherein the two or more colored coating layers comprise two colored coating layers that are the lower-side colored coating layer and the upper-side colored coating layer, and the white pigment is included solely in the lower-side colored coating layer.
